Hello everyone. I have 2012 F250 6.2L gas engine and currently having some issues with it. For some reason it seems to want to enter limp mode if parked on an incline. I've checked just about everything I can think of that would cause this. I've replaced the Throttle body, the throttle position sensor, checked the MAF, confirmed no vacuum leaks exist and I'm starting to lose my mind. I can't reproduce this on demand but this almost always happens when I'm on an incline and I park; After a few seconds the check engine light comes on. The fix is usually turn off and back on except for today where it happened on level ground and the engine would crank but not start. I removed the intake decided to give it a shot and it started. I have various codes thrown for it and I've seen P2195, P0113. P0113 most often.

Currently considering replacing the fuel module and trying that after speaking with a ford parts dealer. Also wondering if the internals of the CATs are busted and is causing a blockage.

Anyone that has suggestions would be appreciated.

 

Did you notice if it only happens with a certain level of fuel in the fuel tank ?

 

I haven't paid much attention to the fuel level but I rarely ever let it get below a half tank.

 

Trying to eliminate one possibility of a defective fuel pump module in the fuel tank.

If one of the tubes has a crack, the pump overcomes that when running, but might allow fuel to drain out when parked and pump is not running and level is low enough for it to drain..
Can sometimes show up as a loss of power because all fuel under pressure is not getting sent to engine.

 

Thank you for the suggestion! The fuel pump module was one the list of possibilities so I'll give it a shot and let you know the results. Thank you again.
